So, you helped me with this before and I think I got the mail to go through now, but now I am getting a different error, which I think may have to do with the aliases. The old server is using lists.luc.edu and the new server is using listservnew.luc.edu, but we still want people to use lists.luc.edu, but it be forwarded to the new server. I am getting this now. 2025-07-22T12:16:14.551521-05:00 lstprdls01 postfix/smtpd[190496]: NOQUEUE: reject: RCPT from unknown[10.18.3.105]: 550 5.1.1 <joetest@lists.luc.edu>: Recipient address rejected: User unknown in local recipient table; from=<jkoral@luc.edu> to=<joetest@lists.luc.edu> proto=ESMTP helo=<DM1PR04CU001.outbound.protection.outlook.com>
